ELM311 Stepper Motor Controller

The ELM311 is an interface circuit for use between high speed logic and four phase stepper motor driver circuits. All of the logic required to provide stepping in two directions is contained in this one 8 pin package. This circuit supports only one mode of operation, the full-step, or single phase w.

ELM311 Features

* Low power CMOS design - typically 1mA at 5V

* Wide supply range - 3.0 to 5.5 volt operation

* Two inputs control Full step motion

* No external timing components

* Completely static operation - will maintain a step position indefinitely

* High curren
